Trainer Freddie Roach is not concerned with the possible working relationship between Floyd Mayweather Jr. and strength/conditioning coach Alex Ariza.

Roach and Ariza had worked together for several years, specifically with Manny Pacquiao, and had a very ugly breakup in 2013.

Ariza was eventually hired by trainer Robert Garcia to work with his fighters.

Things got ugly during last November's Macau fight week for Pacquiao's clash with Garcia-trained Brandon Rios, who had Ariza in his corner for that particular fight. A heated war of words at a local gym became physical when Ariza kicked Roach in the chest.

A few weeks ago Garcia parted ways with Ariza.

A few days ago, Instagram photos and a Youtube video surfaced which showed Ariza assisting Mayweather in camp.

Because Roach and Pacquiao are pushing for a 2015 showdown with Mayweather, BoxingScene.com asked Roach if he was worried about the possibility of Mayweather using Ariza for a Pacquiao fight or the possibility that Ariza might be providing information about the Filipino star.

"Not at all [I'm not concerned]. What does he know? He's not a trainer. I didn't care before [when he worked the corner of Rios]. What he do [for Rios]? Manny won every round of the fight. It's like...who cares," Roach told BoxingScene.com.

Ariza is clearly a good S&C coach, he knows his stuff.
But all the other BS you have to put up with him being around just is not worth it.
He comes across as a groupie instead of just doing his job in the gym.
Kicking Roach and insulting his disability is about as low as it gets, Freddy ...
